Abstract

Durian (Durio zibethinus murr) is a fruit with the 4th commodity in Indonesia which the rind has an antibacterial effect. Durian rind contains active compounds such as flavonoid, alkaloid, saponin, tannin, and triterpenoid which show significant antibacterial activity against Gram-positive bacteria such as Enterococcus faecalis. The purpose of this study is to find out the potency of ethanolic extract of durian rind against Enterococcus faecalis. This study was a quasi-experimental using post-test only control group design with 4 groups of test materials consisting of ethanolic extract of durian rind with concentrations of 10%, 15%, 20%, 25% and 2% chlorhexidine as controls with 6 repetitions. Antibacterial potency tested with a diffusion method (Kirby-Bauer) in Mueller Hinton Agar media. All groups were assessed after 24 hours of incubation period at 37°C. The diameter of inhibition zone was measured with a sliding caliper and data were analyzed using One Way ANOVA test and Post Hoc Games Howel test. The result of this study showed that there were significant differences in the antibacterial potency of ethanolic extract of durian rind (Durio zibethinus murr) against Enterococcus faecalis bacteria between all groups except in the concentration groups of 25% and 20% as well as 15% and 10%. The higher concentration of extract formed a larger clear zone. The conclusion of this study was ethanolic extract of durian rind concentrations of 25%, 20%, 15% and 10% have antibacterial potency against Enterococcus faecalis with an average of 1,69 mm, 1,25 mm, 0,78 mm and 0,42 mm are classified as weak.
